Fig. (3) An unrooted phylogenetic tree constructed from the analysis of the 16S rRNA gene sequences of the alkaliphilic soda lake Bacillus isolates and their closest relatives obtained from the NCBI database. Scale represents the average number of nucleotide substitutions per site. Bootstrap values for every 1000 trees generated are shown at the nodes. The accession numbers of the 16S rRNA sequences for each isolate is shown in brackets.
